Mueller Hg80 Premium Knee Stabilizer review

The Mueller Hg80 Premium Knee Stabilizer sits in Mueller's Hg80 premium line and focuses on comfort with side support. Mueller describes steel springs on both sides of the knee that support it while still allowing the leg to bend and straighten, and a Mueller-exclusive HydraCinn fabric that wicks moisture and has an anti-microbial barrier. The brand recommends it to help control subluxating kneecaps and to support stiff, sore or unstable knees. Sizing is clear: 5 sizes from SM to XXL, measured around the knee from 12 to 22 inches, with centimeter equivalents. We picked it over the Hg80 Premium Knee Brace, which Mueller now lists at a clearance price and a reviewer describes as discontinued. At $89.99 it is the second most expensive brace here, shipping is free only on orders over $100, it has no hinges, and the store page showed no reviews when we checked.
